Chopped Strands

Johns Manville’s chopped strands reinforce thermoplastics, thermosets, gypsum board and nonwoven mats.  We design our fiber glass to your requirements, so your products will perform at optimum levels.  JM fibers may be hidden from view, but their effects are plain to see. We combine our glass fibers with plastics to mold stiffer, stronger and lighter weight products. JM fibers deliver a wide range of benefits that are easy to appreciate.

ThermoFlow® and StarStran® materials reinforce thermoplastic and thermoset resins. Chop-Pak® wet dispersible chopped fiber glass strands are great for creating nonwoven mats.  DuraCore® chop strands are made for either wet or dry delivery gypsum wallboard reinforcement.   

We ship globally!  Contact a regional sales office for details.
